BABY JUMPER.

Application'filed November 4, 1924. Serial No; 747,873.

My invention relates f to improvements` in baby jumpers, of ,the type shownin my United States Letters Patent No.' 1,458,07 7, grantedto meunder date of J une 5th, 1923.

An important object of the invention is to sin'iplify the construction of the device, thereby reducing the cost of itsl manufacture, and: making the same commercially successful.l

A further object of theinvention is to provide a device of the above mentioned character, havingl its principal parts readily separable, and adapted to lbe' assembled without the employment of tools, such as screw drivers or the like. y

.A furthery object of the invention is to provide meansy whereby thev seat may besecured to the movable frame, in a manner to permit of'itsconv'enient removal, for the purpose'ofwashing the same or the lil-ze.

A further object'fofV the invention is to provide a device of the above mentionedl character, which is neaty andV attractive in appearance, and convenient to -be used and handled by the ordinary housewife.y

A Vfurther object of' the invention is'to providev a device ofN the above mentioned character, which while extremely simple in construction, is unusually strong and durable.

Other objects andy advantages of the` invention will be apparent during the course of the following.l description.

In the accompanying, drawingsy formingl a part of this specification, and -in which like. numerals are employed to designate like parts throughout the same,

through theblock of the upper swinging` member, and,

Figure 10 isj asimilar view throughthe;

block of the lower frame or'base'member.

In the drawings, wherein forf the purpose of illustration is shown apreferred embodiment of my invention, the numeral 10 designatesfa base member or frame-which is pref# erably Vformed of wood, with a solid portion or block 11 at one end, carrying spaced longitudinal bars or beams 12 secured thereto by screws or the like. These arms pro-VV ject downwardly below the 4block 11, to suitably elevate the same. floor or platform 13 is arranged upon theV upp'enfaces of the longitudinal beams 12 and is secured thereto by any suitablemeans. M

The numeral "14; designates a vertical standard or support, mounted upon the base member near and spaced from ,its forward end. The standard 14 is `securely arranged' upon the base member and is provided at its lower end with a reduced'eXtension vor tongue 15, iitting` within theopening between the beams 12, as shown. y The numer-f als 16 and v17 designate transverse brace members or blocks having depending'. tongues 18, fitting snugly within the openingsbetweenfthe beams 12. The base member or block 17 is permanently attached tol the beams 12 by screws 19, passing upwardly through theV beams 12. The companion brace member 16 has .a diagonal opening 20, formed therein, for receiving'a bolt 21, equipped with a wing or'thumb nut 22. This clamping bolt 21 is held withinj avdiagonal opening formed in theclampingy member or block 17. .The clamping bolt 21 passes throughy avert-ical slot 23, formed in the.; lower endy ofthe standard 14. j They actionis obtained, whereby thej standa'rdis` securely and rigidly `fastened toV the'. base` vmember or frame. By unscrewingthe wing` nut, the brace rfleinlver` 16 may be Sh'lftedf,A slightlyV from they companion brace' IlflelnberL l17 and the ,Standard released, soithatfit mayl r be separated from the base member or frame. The standard 14 is in the form of a wide fiat plank, board, or strip, and hence it has flat faces, engaging the blocks 16 and 17, whereby the engaging surfaces are large.

The numeral 23 designates a swinging member or frame as a whole, preferably formed of wood, embodying a solid forward portion or block 24, carrying longitudinal beams or arms 25, secured thereto by screws or the like, and extending from the -opposite sides thereof, in spaced relation. The forward portions of the beams or arms 25 are arranged upon the upper rounded end 26 of the standard 14, and this upper rounded end has vertical slots 27, receiving screweyes 28, attached to the beams 25, and depending therefrom. Pivot elements 29 are passed through the upper end portions of the standard and through the' screw-eyes. It is preferred that this pivotal connection between the standard and the upper swinging member be permanent, and the standard may be folded fiat yupon the swinging member or frame 23, as clearly illustrated in Figure 4, when the parts of the device are collapsed.

The numeral 30 designates a suitably stiff retractile coil spring, the lower end of which is looped, as shown at 31, and preferably has detachable engagement with the upper end of an eye-bolt 32, mounted within a longitudinal slot 33, formed in the solid end or portion 11. The eye-bolt carries washers 32 and 33 Yand a nut 34 as shown. The eye" bolt may be adjusted longitudinally within the slot 33 and locked therein in a selected adjusted position. The upper end of the spring is suitably detachably connected with \a bolt 34, arranged within a longitudinal slot 35, formed in the block or solid portion 24 of the upper membei` or frame. This bolt 34 carried washers 37 and 37 and a wing nut 36, and may be adjusted longitudinally, within its-slot and locked in a selected position. By turning the wing nut 36 the tension of the spring 30 may be varied and the effective action of the spring may also be varied, by shifting ittoward or from the standard 14, which is rendered possiblev by the use of the slots 33 and 35, and associated elements. Y

The beams 25 are spaced sufficiently whereby a child may be positioned therebetween, and a tray 38 is preferably perinanently mounted upon the upper sides of t-he beams 25, at points near and spaced from their rearvends. This tray is preferablv equipped with an upstanding flange 39. The rear ends of the beams 25 have'reduced extensions or tongues 40, for engagement with reduced extensions or tongues 41, of a transverse bar 42. These parts are vdetachably held together by bolts 43, carrying f wing nuts 44.

vany other suitable flexible material.l

The numeral 45 designates a blank as .av whole, from which the seat is formed. This blank may be made of canvas, leather, or The blank embodies a central portion 46, side portions 47 a back portion 48, and a forward relatively narrow tongue or strip 49. The side portions have their free ends turned over and stitched as shown at 49, provid-` ing hems 50. The back portion 48 has its free end turned over and stitched at 51, providing a hem 52. This I regard as an important feature of the invention, in combination with the structure of the swinging frame, as it permits of the ready removall of the seat, when desired. It is preferred to employ a seat of this character, but the in. vention is not necessarily restricted to this type of seat, as other forms of seats may be employed, with some degree of success.V

In applying the` seat to the supporting frame, the transverse bar 42 is removed and f the hems 5() passed'upon the rear ends of the bars or arms 25. The transverse ystrip or bar 42 is now passed into the hem 52, and the tongues 40 and 41 are secured to gether by the bolts 43. the seat is now passed through a vertical opening or slot 53, formed in the rear por-y tion of the bottom of the tray38, adjacent to the rear flange 89. The tongue is passed downwardly and the overlapping portions. of the tongue are passed through a flat buckle 54. I prefer to employ a flat buckle of the slide type, as it may be readily adjusted and as it is safer to use with children. The invention is of course in no sense restricted to the use of this particular buckle as the adjacent portions of the tongue may be 'connected by any other suitable means. In the use of the jumper, the child is seated within the seat, and his legs pass forwardly upon opposite sides ofthe approximately vertical tongue 49. The child engages the `platform 14 with his feet, and swings the upper member or frame upon its pivot. The tension of the spring may be so adjusted with respect to the weight of the child, that a slight effort on the part of the child will produce the desired swinging movement. The device is very attractive and amusing to children.

When the device is collapsed, as indicatedr in 'Figure 4, `the upper swinging member is preferably inverted, whereby the tray'38 is positioned" upon the base member, and the standard 14 is folded flat upon the upper surface of the swinging member. The blocks 16 and 17 afford a suitable space forV the spring 30, tray 38, and collapsed seat 45. It is to be understood that the form of vmy invention herewith shown and described, vis to be taken asa preferred example of The tongue 49 of soA be resorted to without departing from the spirit of my invention or the scope of the sub'oined claims.
